INTRODUCTION: Lumbar epidural block is an effective and routinely used technique for labor pain relief, and the combined spinal-epidural block has the benefit of using lower doses of local anesthetics and rapid onset of analgesia. The objective of this study was to evaluate the effectiveness and safety of two anesthetic techniques: combined spinal-epidural block and continuous epidural block in pregnant women for labor analgesia. METHODS: Eighty patients, ASA II and III, with cephalic presentation and cervical dilation between 5 and 6 centimeters, undergoing labor analgesia, allocated in two groups according to the anesthetic technique: combined spinal-epidural (GI) and continuous epidural (GII)...

BACKGROUND: A single dose injection or continuous infusion of local anesthetics into the joint space is considered to be a well-defined analgesia technique. The aim of this study was to investigate the chondrotoxic and apoptotic effects of single-dose intra-articular injection of levobupivacaine and bupivacaine on rabbit knee joint tissues. MATERIALS AND METHODS: The animals were allocated into two groups each containing 20 rabbits. 0.5% levobupivacaine (Group L) and 0...

INTRODUCTION: Hip surgery is a major surgery that causes severe postoperative pain. Although pain during rest is usually considerably reduced mobilization is important in terms of thromboembolic complications. The quadratus lumborum block is a regional analgesic technique that blocks T6-L3 nerve branches. This block may provide adequate analgesia and reduce opioid consumption after hip surgery. CASE REPORT: We performed continuous quadratus lumborum type 3 block in two patients who underwent hip arthroplasty...

INTRODUCTION: Hepatic ischemia-reperfusion injury is a common pathophysiological process in liver surgery. Whether Propofol can reduce myocardial ischemia-reperfusion injury induced by hepatic ischemia-reperfusion injury in rats, together with related mechanisms, still needs further studies. OBJECTIVE: To investigate if propofol would protect the myocardial cells from apoptosis with hepatic ischemia-reperfusion injury. METHODS: Male Sprague-Dawley rats (n=18) were randomly allocated into three groups: Sham Group (Group S, n=6), Hepatic Ischemia-reperfusion Injury Group (Group IR, n=6) and Propofol Group (Group P, n=6)...

BACKGROUND: Adequate preoperative fasting is critical in preventing pulmonary aspiration of gastric content. We proposed to study the sonographic gastric content dynamics after the ingestion of liquid or solid food in healthy volunteers and confront it with current guidelines for preoperative fasting times. METHODS: We performed a prospective, crossover, evaluator-blinded study involving 17 healthy volunteers of both sexes. Each participant fasted for 10h and was subjected to a baseline gastric ultrasound, intake of 400mL of coconut water or a 145g, 355kcal meat sandwich, and sonographic gastric evaluations after 10min and every hour until the stomach was completely empty...

BACKGROUND AND OBJECTIVES: The emerging use of endovascular therapies for acute ischemic stroke, like intra-arterial thrombectomy, compels a better understanding of the anesthetic management required and its impact in global outcomes. This article reviews the available data on the anesthetic management of endovascular treatment, comparing general anesthesia with conscious sedation, the most used modalities, in terms of anesthetic induction and procedure duration, patient mobility, occlusion location, hemodynamic parameters, outcome and safety; it also focuses on the state-of-the-art on physiologic and pharmacologic neuroprotection...

BACKGROUND AND OBJECTIVES: Propofol is commonly employed as a hypnotic agent to perform electroconvulsive therapy, but it exhibits also anticonvulsant properties. The main objective was to study the effect of the weight-adjusted dose of propofol on duration of the electrical seizure. Secondary objectives were to study the effect of absolute dose of propofol on duration of electrical seizure, the effect of both absolute and weight-adjusted doses on values of bispectral index, and the influence of blood chemistry on anticonvulsant effect...

Thoracic trauma with rib fractures is a challenging condition due to the severe associated pain. Uncontrolled pain impairs breathing and an adequate pain control is necessary to provide comfort and to avoid further complications. Serratus Anterior Plane block is a procedure safe and easy to accomplish. The authors describe a case of thoracic trauma with rib fractures and respiratory compromise. Pain control was only achieved after performing a Serratus Anterior Plane block. The technique was done as described in the medical literature with placement of a catheter...

BACKGROUND AND OBJECTIVES: An ultrasound guided femoral nerve block is an established analgesic method in patients with a hip fracture. Elevated cytokine levels correlate with poor patient outcomes after surgery. Hence, the aim of the study was to describe the levels of tumor necrosis factor-α after an ultrasound-guided femoral nerve block in elderly patients having a femoral neck fracture. METHODS: A total of 32 patients were allocated into two treatment groups: 16 patients (femoral nerve block group; ultrasound-guided femoral nerve block with up to 20mL of 0...

BACKGROUND AND OBJECTIVES: Bilateral quadratus lumborum block has been described for major abdominal procedures when sepsis is present, because risks associated to epidural are considered elevated. In an open aortic surgery, a single-shot bilateral quadratus lumborum block type 1 may be an alternative to thoracic epidural block for post-operative analgesia in a patient having an increased cumulative risk for thoracic epidural hematoma. CASE REPORT: A 56-year-old female patient presenting controlled hypertension, chronic renal disease stage 3b, dyslipidemia and a platelet count of 102,000/μl, and taking aspirin, was scheduled for bilateral aortoiliac endarterectomy...

BACKGROUND: After advancement of cardiovascular surgery, there is also exponential development of anesthetic techniques in this field. Patients with increasing clinical complexity challenge cardiac anesthesiologists to keep constantly updated. An evaluation of Brazilian's cardiovascular anesthesia fellowship at Dante Pazzanese Institute of Cardiology has been made and information has been collected to evaluate the fellowship program in cardiovascular anesthesia. METHOD: Target participants were made up of former fellowships, contacted via e-mail containing an invitation to voluntarily participate...

BACKGROUND AND OBJECTIVES: Conjoined twins are monozygotic twins physically joined at some part of the body. This is a rare phenomenon, estimated between 1:50,000 to 1:200,000 births. The objective of this report is to present the anesthetic management and the perioperative challenges for a separation surgery. CASE REPORT: Thoraco-omphalopagus twins were diagnosed by ultrasound and were followed by the fetal medicine team of the service.

BACKGROUND AND OBJECTIVE: Palliative sedation is a medical procedure that has been used for more than 25 years to relieve refractory symptoms not responsive to any previous treatment in patients with no possibility of cure and near the end of life. Many uncertainties persist on the theme regarding definition, indications, decision making, most appropriate place to perform the procedure, most used drugs, need for monitoring, fluids and nutritional support, and possible ethical dilemmas...

BACKGROUND AND OBJECTIVES: Ultrasound-guided thoracic paravertebral block is usually considered a good alternative to epidural thoracic for anesthesia and pain control in thoracic and breast surgery. Furthermore it has also been used during abdominal surgery lately, especially hepatic and renal surgery. However, its role is poorly defined in this context. The purpose of this report was to highlight the role of thoracic paravertebral block in providing effective anesthesia and analgesia during both the abdominal surgical intervention and pain control in post-operative period, avoiding possible complications which general anesthesia may arise, which are fairly common in patients with chronic obstructive pulmonary disease and similar comorbidities...
